Abstract: Provided is a process for obtaining solid cellulose, such as a cellulose solidified article or cellulose shaped article, from a cellulose solution without causing discharge of large amounts of waste liquids and environmental issues such as large energy consumption. The process produces solid cellulose through the steps of (A) dissolving cellulose in a solvent (s1) to give a cellulose solution, where the solvent (s1) includes at least one onium hydroxide in a content of from 45 to 85 percent by weight and water in a content of from 15 to 55 percent by weight, and the at least one onium hydroxide is selected from the group consisting of quaternary phosphonium hydroxides and quaternary ammonium hydroxides; (B) bringing the cellulose solution into contact with a poor solvent (s2) to precipitate cellulose as a cellulose solidified article; and (C) separating and collecting the cellulose solidified article.
